I have two 256GB NVMe flash devices installed in each of my servers, and one is fully allocated as a single datastore while the other storage device has 64GB of the 256GB capacity assigned as virtual flash read cache. However, the other ~192GB of storage on that devices does not become visible for datastore creation or anything else.
What else can I use the remaining storage for? Is there a way I can assign a datastore to it? After all random access on the device is very fast, and I only need that 64GB of it at most for the vflash read cache. Are there other configurations in VMware that can utilize this remaining storage that I am not aware of? I say ‘other configurations’ because I am thinking also about third-party iSCSI acceleration-via-flash-caching proprietary modules like VirtuCache (vnx2) etc but am not aware of what else could benefit from that remaining storage space.
Thanks in advance,
